DEVICE FOR CONNECTING- MARBLE SLABS.

Specificationk of Letters Patent. Application :tiled .Tune 16, 1906. Serial No. 322,114.

Patented June 15, 1909.

To all whom it may concern:

Be it known that l, FRANK O. ySTREED, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State rof Minnesota, have invented certain new and useful improvements in Devices for Connecting Marble Slabs; and l do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable Others skilled in the art to which it appertains to make and use the same. l

My invention has for its especial object to provide an improved device for connecting marble slabs, where the one slab extends at right angles or obliquely to the other, and to .this end it consists of the novel devices and combinations of devices hereinafter described and defined in the claim.

yIn the accompanying drawings which Iillustratethe invention, like characters indicate like parts throughout the several views.

Referring to the drawings: Figure l is a view in side elevation showing two .marble slabs connected by my improved device, some parts being broken away. Fig. 2 is a front elevation of the parts shown in Fig. l,

Y some parts being sectioned on the line a02 m2 `Lit of Figs. l and 3, some parts bein broken "away, and 3 is a horizonta section taken approxlmately on the line m3 m3 of Fig. ,2, some4 parts being broken away.

The numeral 1 indicates what may be designated as the wall slab, and 2 what may be designated a stall or partition slab' The slab l may be assumed to be secured at its backagainst a wallfby the usual or any suitable means.

Referring to the arts of thewimproved coupling, the numerall indicates an inverted approximately U-shaped saddle bracket, the depending sides of whicfh areprovided at their'rear edges with oppositely extended flanges 4. This saddle bracket 3 is adapted ,to be slipped down and over the upper edge of the rear portion of the slab 2, with its flan es .4 bearing against the adjacent face of t e slab l.

Cap nuts 5 lwork Iloosely in seats formed in the flanges 4, and similar cap nuts 6 work loosely through seats in the depending side webs of the saddle bracket 3. These cap nuts 5 and 6 are provided with heads that are countersunk into the flanges or webs with which they engage, and are provided with slightly rounded outer surfaces and with grooves 7 that adapt them to be turned by means of a screw-driver.

The slab 1 is provided with perforations 8, in which the sleeve portions of the cap nutsI 5 work' loosely; and likewise the slab 2 is formed with perforations 9, in which the sleeve portions of the cap nut 6 work loosely. At the back of the slab 1 is a metal strap or clamping bar 10 that overlaps the inner extremities of the perforations 8. Small threaded rods or studs l1 are screwed into the sleeve portions of the cap'nuts 5, and fit the threaded seats in the clamping bar 10. Similar threaded rods or studs 12 are screwed into the sleeve portions of the f Furthermore, a large range of adjustabilityy is afforded, since the said screw rods 11 are adjustable both in the cap nuts 5fand in the clamping bar 10; while the said screw rods 12 are each adjustable in the two alined cap (nuts.

The device Qdescribed, while simple, con- .venient and eiiicient for the purposes had in View, is also of small cost, and when applied has a very neat and finished appearance. The device above described may be used for connecting various kinds of slabs or plates other than marble slabs, and might, for instance, be used to connect panes of plate glass.

I claim as my invention:

The combination with a U-shaped saddle bracket 3 having projecting flanges 4, of a `clamping bar l0, cap nuts l5, heads which are 'counter-sunk into\ said flanges 4, rods' 11 threaded at both ends, and having threaded engagement with said bar 10 and with the In testimon whereof I aiIix my signature slleev portions gf 'said hcaphmts, axlally in presence o two witnesses.
